B Efficiency Power Supplies

↪ Notes: 5 year warranty, OCP is set way higher than necessary on the minor rails.

↪ Notes: Although OCP is set reasonably (118% on 12V), the platform is at its limit and cannot handle the increased stress, as ripple gets out of control.

↪ Notes: Qualified for 80+ Silver in testing

↪ Notes: Cybenetics Silver

↪ Notes: ODM is Dongguan Changhu Electronics Co. Ltd.

↪ Notes: Also known as CSK[w]H. Not printed on the logos.

↪ Notes: X8 might be a clone of CWT's GPK platform, but is similar to the M5 platform (not very good.)

↪ Notes: X8 might be a clone of CWT's GPK platform, but is similar to the M5 platform (not very good.)

↪ Notes: 2 year warranty. 650W: 576W on 12v.

↪ Notes: Low quality fan, 85C bulk cap.

↪ Notes: Terrible ripple suppression, especially on 12V (well over 100mV under full load), OCP is not set properly, low efficiency, low quality fan.

↪ Notes: Looks exactly the same as the regular System Power 10 internally. Unless later testing proves the above issues are not present, detier to E.

↪ Notes: Sleeve bearing fan, during OPP testing at around 30% of the 500W model do the minor rail falls out of ATX specification.

↪ Notes: Receives a "-" subtier due to its age. Only kept for legacy purposes as it is still listed on Chieftec's website.

↪ Notes: 3 year warranty; 85C bulk cap, and not one of particularly good quality, either.

↪ Notes: 3 year warranty; 85C bulk cap, and not one of particularly good quality, either.

↪ Notes: OPP is functional but offers only a 7% increase over the nominal value, beyond which the rails fall out of ATX spec for the 1000W model.

↪ Notes: Doesn't claim OCP.

↪ Notes: Basically G1208 updated to ATX 3.1

↪ Notes: Identical internally to the MasterWatt Bronze. Only difference is the exterior appearance.

↪ Notes: Basically G1208 updated to ATX 3.1, no 12VHPWR.

↪ Notes: Basically G1208 updated to ATX 3.1; broke during 5V SCP. Possible bad sample? No 12VHPWR.

↪ Notes: Black "CX" lettering on gray label; Double-sourced between GW & CWT; technically qualified for 80+ Silver but badged as Bronze.

↪ Notes: Technically 80+ Silver without RGB on

↪ Notes: Poor ripple suppression on the minor rails. Uses semi-digital PFC, 7 year warranty. Can get loud (in excess of 40dbA) under heavy load.

↪ Notes: Gray label

↪ Notes: Gray label

↪ Notes: White "CX" lettering on black label; Identical to the CV aside from exterior design.

↪ Notes: Green "CX" lettering on black label. Tier should not preclude the usual caveats associated with used/very old power supplies.

↪ Notes: Green "CX" lettering on black label. Detiered to C- due to age.

↪ Notes: Grey label

↪ Notes: Grey label

↪ Notes: White "CX" lettering on black label; Identical to the CV aside from exterior design.

↪ Notes: Green "CX" lettering on black label. 85C caps all around, 30C rated operating temp, avoid.

↪ Notes: Green "CX" lettering on black label. 85C caps all around, 30C rated operating temp, avoid.

↪ Notes: Mediocre quality capacitors.

↪ Notes: Platform is certified for Gold, might have only hit Bronze due to modular interface

↪ Notes: Internals appear to be variable based on region/batch.

↪ Notes: Subpar component quality, with highly set protections and OOS 3.3V transient response.

↪ Notes: Low component quality, w/ highly set OCP/OPP & OOS 3.3V transient response. Not quite ATX 3.X by failing low load efficiency. 600W 12+2 cable.

↪ Notes: Subpar component quality, with poorly tuned protections, 5V OCP incorrectly set allows for >135mV of ripple. OOS 3.3V transient response.

↪ Notes: Good electrical performance for the category, decent component quality, protections are set reasonably.

↪ Notes: ATX 3.1 is claimed, but the unit fails to meet the spec due to poor ATX 3.1 excursion response. Treat as ATX 2.x.

↪ Notes: Single EPS cable, failing or near failing 3.3V transient response, hold-up time not within ATX specifications.

↪ Notes: Same internals as the Revobron, simply a 2.0 refresh.

↪ Notes: 850W uses ARGB fan + housing and comes in black and white models. 3 year warranty.

↪ Notes: No OCP on 12V. High RMA rate due to MLCC cracks, similar to other HEC-built EVGA PSUs

↪ Notes: OCP on 12V doesnt exist. OPP is set too high. Sleeve bearing fan.

↪ Notes: Died after OPP testing. OTP claimed but not tested. Sleeve bearing fan. Failed 3.3V transient testing

↪ Notes: Platform is an old Super Flower design, but is actually produced by RSY.

↪ Notes: OCP (12V) is either faulty or not present; faulty OCP on 3.3V allowing for OOS operation, and no OTP per Aris' review. Very loud (50dBA+).

↪ Notes: Identical to the Hydro Pro, simply the semi modular variant.

↪ Notes: Not enough conclusive data but platform is well reviewed.

↪ Notes: Sleeve bearing fan.

↪ Notes: Europe only

↪ Notes: OCP on both the 3.3V and 5V lines is either faulty or set in excess of 330%, which is unacceptable. Bad electrical performance (severely OOS).

↪ Notes: 500W variant's +12V output is rated for 480W. Rifle-bearing fan (PY-1225M12S)

↪ Notes: Actual 12V line output is 50 watts less than the model name (despite being DC-DC), numerous minute issues; overall suboptimal quality.

↪ Notes: Platform confirmed through overhead and internal shots provided by the manufacturer.

↪ Notes: SI model, however it appears to be identical to the MP-B.

↪ Notes: Platform is GPN (or at least very similar), even though the model number indicates it to be GPK.

↪ Notes: Semi-modular A-BN. See internal shots here.

↪ Notes: Components are variable based on batch.

↪ Notes: Components are variable based on batch.

↪ Notes: A-BN with 300W 12VHPWR connection. Claims sleeve bearing, unknown quality fan.. Does not claim ATX 3.0 compliance.

↪ Notes: Single-rail. See review. Poor transient response on 3.3V, rifle bearing fan. OTP isn't claimed or tested, but is supported by the supervisor IC.

↪ Notes: 130mV+ of ripple on all rails (out of spec) at only 60% load; failed to meet even 80+ Bronze. See Rear Shot and Output Specification Label.

↪ Notes: See teardown here

↪ Notes: Still produced according to MC stock

↪ Notes: Still produced according to MC stock

↪ Notes: Low quality sleeve bearing fan, ripple exceeds ATX specification, low quality capacitors, and a 3 year warranty.

↪ Notes: Platform was swapped from ATX-0600 to ATX-0200 sometime around 2024. No way to tell the original from the swap. Avoid.

↪ Notes: Platform was swapped from ATX-0600 to ATX-0200 sometime around 2024. No way to tell the original from the swap. Avoid.

↪ Notes: Internal shots show the unit using the same "ICB" (in reality rifle bearing) fan as the SilverStone Triton Rx.

↪ Notes: Costdown of the G12 GC; cheaper components, all Chinese caps, and an even cheaper fan; downgraded to Bronze eff.

↪ Notes: Claims only SCP, OPP, and over/under voltage. OCP not claimed on any rail.

↪ Notes: EU/JP only? No stated manufacturer warranty outside of mandated EU 2 year warranty.

↪ Notes: Subpar hold-up time.

↪ Notes: Actual 12V capacity is 456W. Does not claim OTP. ARGB fan controlled via motherboard header. Hong Hua rifle bearing fan.

↪ Notes: Actual 12V capacity is 456W. Does not claim OTP nor OCP. Assumed to be similar to ET500-ARGB.

↪ Notes: Does not claim OCP on any rails. Minimal information available.

↪ Notes: Limited information.

↪ Notes: Sleeve-bearing fan. OCP untested.

↪ Notes: OCP doesn't work properly on +12V, unit experiences a huge voltage drop to 10.92V on +12V. Avoid until further testing.

↪ Notes: Transient response was tested but values were left out. OPP is set very high, but the PSU handled it and shut down safely and properly.
